s'frrss CONCRETE TIE.

Application filed July 29, 1920.

To all whom it may concern Be it known that I, THOMAS D. lVnIoH'r, a citizen of the United States of America, residing at Springville, in the county of Saint Clair and State of Alabama, have inrented new and useful Improvements in Concrete Tics, of which the following is a specification.

The object of the invention is to provide a railroad tie of a construction which will provide a proper support for the rails, as a substitute for the wooden ties now ordinarily employed and which will have the improved means for securing the rails in their proper relation while permitting a sufficient cushioning of the same to avoid the objections ordinarily urged against concrete and metallie-ties as heretofore constructed, and with th s object in View the invention consists in the construction and combination of parts of which a preferred embodiment is shown in the drawings wherein:

Figure 1 is a perspective view of a tie embodying the invention and showing at one end thereof a portion of a rail secured in operative position.

Fig. 2 is a plan view of the tie.

Fig. 3 is a bottom plan view of the same, the filler being omitted.

Fig. i is a longitudinal sectional view on the plane indicated on the line 1-4: of Fig. 1 with the filler omitted.

Fig. 5 is a transverse section on the plane indicated by the line 55 of Fig. 1.

Fig. 6 is a detailed view of one of the rail clamping jaws.

The tie embodies essentially a shell or box 10, preferably of metal, open at its upper and lower sides, the lower side thereof being spanned transversely by the brace bars 11, flush with the lower edges of the side walls of the shell, and the upper side thereof being spanned by transverse seat bars 12 which are arranged respectively in the planes of the railroad rails 13, indicated in Figs. 1 and 4, or at an interval corresponding with the proposed distance between the rails which are to be seated upon the tie.

The rest bars'12 are preferably depressed slightly below the upper edges of the side walls of the shell, as indicated clearly in Fig. 5, so that the base or foot 14% of the rail 13 is spaced slightly above the surface of the corresponding rest bar and a minute dis- Specification of Letters Patent.

tance also above theupper edges of the side walls. 7

Arranged in operative-relation with each rest bar is a rail clamp consisting of cooperating jaws 15 adapted to extend over and engage the foot of the rail, as shown in 4f, the shank portions 16'of said jaws belng fulcrumed by means of pins 17 which are fitted in vertical slots 18 formed in longitudinal reinforcing bars 19 preferably eX- tending from end to end of the shell and terminally secured to the end walls thereof by means of rivets 20, as indicated'in Fig. 3. The members or jaws of the clamp are ad-- justably connected by means of a bolt 21 extending througa registering openings in said jaws and fitted with a nut 22, said bolt eX- tendin between the rest bar 12 and the undersurface of the rail foot midway between and parallel with the upper edges of the side walls of the tie shell to the end that there is a possibility of a slight yielding movement of the rail sufficient to cushion any shock or jar applied thereto, such yielding movement being communicated from the rail foot through the adjusting rod or bolt 21 to the rest bar 12, and the jaws being adapted for corresponding yielding move ment by reason of the engagement of the fulcrum pins 17 with the slots 18 in the lower edges of the longitudinal bracing members 19.

The interior of the shell is occupied by a filler 23 of concrete or cement which, however, is omitted adjacent to the jaws of the clamping members, as indicated at 24, to permit of the manipulation of the jaws to either clamp or release the rails, it being obvious that by the arrangement of the adjusting rods or bolts 21 near theplanes of the upper edges of the side walls of the shell, the fastening or unfastening of the rails may be effected without displacing a tie or dlsarranging the elements thereof.

Having described the invention, I claim: 1. A rail t1e consisting of a metallic shell having parallel side walls and provided with a filler of concrete, longitudinal reinforcing bars arranged in parallel relation with the side walls of the shell, transverse bottom braces connecting the side walls beneath the lower edges of said reinforcing bars, transverse rest bars disposed adjacent to the upper edge of the shell in the planes of the rails supported by the tie, and clamping means for securing the rails in position, and consisting of relatively movable jaws pivotally mounted upon said longitudinal reinforcing bars.

2. A rail tie consisting of a metallic shell having parallel side walls and provided with a filler of concrete, longitudinal reinforcing bars arranged in parallel relation with the side walls of the shell, transverse bottom braces connecting the side walls beneath the lower edges of said reinforcing bars, transverse rest bars disposed adjacent to the upper edge of the shell in the planes of the rails supported by the tie, and clamping means for securing the rails in position consisting of adjustably connected jaws arranged between the planes of and pivotally mounted upon said longitudiiml rein forcing bars;

3. A rail tie consisting of a metallic shell having parallel side walls and provided with a filler of concrete, longitudinal reinforcing bars arranged in parallel relation with the side walls of the shell, transverse bottom braces connecting the Side walls beneath the lower edges of said reinforcing bars, transverse rest bars disposed adjacent to the upper edge of the shell in the planes of the rails supported by the tie and clamping means for securing the railsin position con sisting of jaws having transverse fulcrum pins engaged with slots in said longitudinal reinforcing bars, and adjusting rods or bolts connecting said jaws.

4. A rail tie consisting of a metallic shell having parallel side walls and provided with a filler of concrete, longitudinal reinforcing bars arranged in parallel relation with the side walls of the shell, transverse bottom braces connecting the side walls beneath the lower edges of said reinforcing bars, transverse rest bars disposed adjacent to the upper edge of the shell in the planes of the rails supported by the tie, and clamping means for securing the rails in position COD": sisting of jaws having transverse fulcrum pins engaged with slots in said longitudinal reinforcing bars, and adjusting rods or bolts connecting said jaws and extended he- 'tweenthe planes of said rest bars and the bases of the rails seated upon the tie.

In testimony whereof 1 affix my signature.
